Furthermore, our analysis results indicate that the cooling mode

" Loss to Ambient" is an effective cooling mode. Therefore, the imposition of surveillance requirements on non-operating MDHR System components is neither justified nor desired.

~~

~

~

The proposed surveillance requirements have the following bases:

1.

MDER System flowrate of 50 gpm has been specified to establish the required RCS flowrate for the removal of the generated decay heat.

2.

MDER System heat exchanger outlet temperatures have been specified based on the intent to permit the RCS bulk temperature to not 0

exceed approximately 150 F and to keep the RCS bulk te=perature above an acceptable minimum te=perature for Boron solubility conditions.
